In September 1938, Hitler had been in power for more than five years, & had abrogated most of the constraints placed on German militarism by the Treaty of Versailles. Earlier that year he had forced Austria into his Third Reich without a single shot fired, & his sights were set on Czechoslovakia. It was in this climate that a coup was born, led by Lieutenant Colonel Hans Oster of German military leaders, members of the Berlin police, local troop commanders, civil authorities, religious leaders, & a courageous group of resisters who assembled in a mission to unseat, & even kill, Hitler. The Oster Conspiracy of 1938 mines the cultural & political milieu of post-WWI Europe, the forces & personal histories that motivated the group to such decisive & dangerous action, & the catalyst of their ultimate failure. This is narrative history at its best: revelatory, well documented with archival material, people with a rich cast of characters, fast-paced, & highly provocative.
